The UNESCO Institute for Statistics (UIS) is the statistical office of UNESCO and is the UN depository for cross-nationally comparable statistics on education, science and technology, culture, and communication.

The UIS was established in 1999. Based in Montreal, Quebec, Canada, it was created by a collaboration between Université de Montréal, the INRS and UNESCO to provide statistics for the UN.

The institute serves member states of UNESCO as well as intergovernmental and nongovernmental organisations, research institutes, universities, and citizens. All data is available for free.

Its offices are based at Côte-des-Neiges on the main campus of Université de Montréal, in building 3333 Queen-Mary Road.

The institute provides education data to many global reports and databases, such as the SDG global database of the UN Stats Division, the Global Education Monitoring Report, World Development Indicators and World Development Report (World Bank), Human Development Report (UNDP), and State of the World's Children (UNICEF).

Sex-disaggregated indicators are systematically integrated into all UIS data collections.

All UIS data is freely available in different formats.

Designed for expert users, the UIS database is an online resource that provides country profiles, indicators, and data series in UNESCO's fields of competence, tools to build statistical tables, related documentation, and metadata. Developers and researchers can also use an API to download UIS data in machine-readable formats.
